MONTREAL - On June 7, 2011 Montreal police officers shot and killed two men. Mario Hamel had spent several years at a shelter, but was reportedly getting his life back together and had once again moved into a permanent home. Patrick Limoges was bicycling on his way to work.

Police apparently opened fire when Hamel charged at them with a knife, and Limoges was an innocent shot by mistake.

RCMP officer-turned-community activist Will Prosper says police have many options when dealing with violent people, and that a gun should only be a last resort.

In an interview with Todd van der Heyden, Prosper said that when he was in a similar situation he and his partner were able to disarm a man by hitting his arm with a telescopic baton.
